- Rubble: roughly broken stones of any shape bounded in mortar.- Ashlar Masonry: is the strongest and most suitable stonework for monumental architecture, which consists of regularly cut blocks (usually rectangular).
2) Find 2 statements of comparison and contrast.
- The best stone (and brick) bonding is that in which blocks are placed so that the vertical joints in one course are not about the joints in the course above and below, since the stone resists deformation better than any bonding material.- Although it has generally been replaced as a structural material by cheaper and more efficient manufactured products, it is still widely used as a surface veneer for its practical and expressive qualities.
3) Find 2 statements expressing cause and effect.
- Because of its weight and the precision with which it can be shaped, stone masonry (in contrast with brick) does not depend on strong bonding for stability where it supports only direct downward loads.- But this roofing requires so many columns that unvaulted masonry buildings are almost always combined with floors and covering in wood.
4) Find 2 adjectives in the superlative form, and 2 in the comparative form.
- In most areas where stone is available, it has been favoured over other materials for the construction of monumental architecture.- The strongest and most suitable stonework for monumental architecture is ashlar masonry, which consists of regularly cut blocks (usually rectangular).- Although it has generally been replaced as a structural material by cheaper and more efficient manufactured products, it is still widely used as a surface veneer for its practical and expressive qualities.- Since the stone resists deformation better than any bonding material.
